What is opp?

OPP, or Object-Oriented Programming, is a programming paradigm based on the concept of "objects", which can contain data, in the form of fields (often known as attributes), and code, in the form of procedures (often known as methods).

Key principles of OPP include:

• Encapsulation: Bundling data and methods that operate on that data within a class, hiding the internal implementation details from the outside world. This promotes data integrity and reduces complexity.
• Inheritance: Creating new classes (child or derived classes) based on existing classes (parent or base classes). This allows for code reuse and the creation of hierarchical relationships between classes.
• Polymorphism: The ability of an object to take on many forms. This allows you to write code that can work with objects of different classes in a uniform way, as long as they share a common interface or inheritance.
• Abstraction: Simplifying complex reality by modeling classes appropriate to the problem. It focuses on essential characteristics, hiding unnecessary details.

Other important concepts in OPP include:

• Classes: Blueprints for creating objects. They define the attributes and methods that an object of that class will have.
• Objects: Instances of a class. They are the concrete entities that exist in memory and can be manipulated.
• Methods: Functions that are associated with a class or object. They define the behavior of the object.
• Attributes: Variables that are associated with a class or object. They store the data that describes the object.

OPP aims to improve code reusability, maintainability, and scalability. Popular languages supporting OOP include Java, C++, Python, and C#.
